Same problem in pulseaudio 1:11.1-1ubuntu7.4 on Linux Mint 19.3 Tricia base: Ubuntu 18.04 bionic.
Speakers are muted at boot and remains muted after plug and unplug headphones. Only can be activated from alsamixer, unmuting the headphones while the headphones are unplugged. Both speakers and headphones muting seems to be controlled in the Headphones area using alsamixer. I've "solved" it in a not very good way, keeping automute activated in alsamixer, modifiyng /usr/share/pulseaudio/alsa-mixer/paths/analog- output-headphones.conf and executing a bash script at boot (sonido.sh) with the command "amixer set -c 0 Headphone unmute 100%" in order to prevent the speakers being muted. Tomorrow I'm going to send more details and try to reproduce the same bug using Xubuntu 18.04.
